Abstract
An electrical machine includes an electric motor, a cooling jacket over the electric motor, and a power inverter having multiple AC power outlets. The electrical machine also includes an elongated busbar having an end adjacent to and coupled to an AC power outlet. The other end of the elongated busbar is adjacent to and coupled to the electric motor. The elongated busbar traverses from one end of the electric motor to a second end of the electric motor over, and in thermal contact with, the cooling jacket so as to reduce a high temperature at the electric motor to a low temperature at the AC power outlet.
